“…There is a need to improve agricultural productivity through advanced agriculture production techniques. The country is listed among the countries severely affected by climate change [74] despite being a low producer of CO 2 gasses [75] because of its increasing dependence on agriculture for food and fiber needs [76]. The role of extension services is also very important for spreading updated scientific information to farmers.…”

This study aims to explore the casual relationship between agricultural production, economic growth and carbon dioxide emissions in Pakistan. An autoregressive distributed lag (ARDL) model is applied to examine the relationship between agricultural production, economic growth and carbon dioxide emissions using time series data from 1960 to 2014. The Augmented Dickey–Fuller (ADF), Phillips–Perron (PP) and Kwiatkowski–Phillips–Schmidt–Shin (KPSS) tests are used to check the stationarity of variables. The results show both short-run and long-run relationships between agricultural production, gross domestic product (GDP) and carbon dioxide emissions in Pakistan. From the short-run estimates, it is found that a 1% increase in barley and sorghum production will decrease carbon dioxide emissions by 3% and 4%, respectively. The pairwise Granger causality test shows unidirectional causality of cotton, milled rice, and sorghum production with carbon dioxide emissions. Due to the aforementioned cause, it is essential to manage the effects of carbon dioxide emissions on agricultural production. Appropriate steps are needed to develop agricultural adaptation policies, improve irrigation facilities and introduce high-yielding and disease-resistant varieties of crops to ensure food security in the country.

“…However, tendency is largely of increasing except for average and minimum discharge for Koshi basin ( Figure S3), and increasing in case of maximum discharge and decreasing in case of average and minimum discharge for Koshi basin (Figures S2, S3 and S4). Month wise trend ( (Smadja et al, 2015). Average monthly discharge plot ( Figure S5) shows highest average discharge for August in all three basins, while lowest average discharge for Manas basin is in January and for Gandaki and Koshi basins in March.…”

Snow governs interaction between atmospheric and land surface processes in high mountains, and is also source of fresh water. It is thus important to both climate scientists and local communities. However, our understanding of snow cover dynamics in terms of space and time is limited across the Hindu Kush Himalaya (HKH) region, which is known to be a climatically sensitive region. We used MODIS snow cover area (SCA) data (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012), APHRODITE temperature data (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007), and monthly long term in-situ river discharge data of the Gandaki (1968Gandaki ( -2010, Koshi (1977Koshi ( -2010 and Manas (1987Manas ( -2004 basins to analyse variations among four basins. We gained insights into short term SCA and temperature, long term discharge trends, and regional variability thereby. Strong correlations were observed among SCA, temperature and discharge thereby highlighting the strong nexus between them. Temporal and spatial snow cover variability across the basins is strongly coupled with the variability of two weather systems: Western Disturbances (WD) and Indian Monsoon System (IMS), and strongly influenced by topography. Manifestation of these variability in terms if downstream discharge can have repercussion to water based sectors: hydropower and agriculture, as low flow seasons is seen affected. This study adds to our knowledge of snow fall and melt dynamics in the HKH region, and intra-annual snow melt contributions to downstream discharges. The study is limited by short span of data and it is desirable to perform a similar study using data representing a much longer time span.

“…C'est le cas au Népal, dans la région du Solu-Khumbu, où la présence de l'Everest a favorisé le développement du trekking, forme de tourisme pédestre itinérant pratiquée dans des espaces naturels d'accès difficile (Sacareau, 1997). Localisé dans la partie orientale de l'Himalaya Tourisme, gestion sociale de l'eau et changement climatique dans un territoir... Journal of Alpine Research | Revue de géographie alpine, 108-1 | 2020 népalais, le massif de l'Everest reçoit en été de fortes précipitations de mousson, d'environ 3000 mm par an dans les moyennes montagnes du Haut Solu, à moins de 900 mm dans les hautes montagnes du Khumbu (Smadja et al, 2015). L'eau de fonte de la neige et des glaciers, combinée à celle des pluies de mousson, alimente les rivières, dont les débits connaissent une forte amplitude entre l'étiage de l'hiver et les hautes eaux de l'été.…”

Depuis une dizaine d'années cependant, des équipes pluridisciplinaires françaises et népalaises mènent des recherches conjointes autour de cette relation (Wagnon et al, 2008 ;Aubriot et al 2012 ;Faulon, 2015 ;Puschiasis, 2015 ;Savéan et al, 2015 ;Smadja et al, 2015 ;Jacquemet, 2018).

“…Malgré huit ans de recherches fondamentales en hydrologie et glaciologie, beaucoup d'incertitudes demeurent sur des effets avérés du changement climatique. Toutefois, les populations enquêtées font état d'hivers moins rigoureux, de chutes de neige moins fréquentes et moins abondantes, qui couvrent le sol moins longtemps, d'un dégel plus précoce des torrents, et de précipitations inhabituelles en septembre et octobre, moment où débute la saison touristique (Smadja et al, 2015).…”
